MACHINE FOR WINDING HEAVY TWINE.

SPECIFICATION forming part of Letters Patent No. 666,290, dated January22, 1901.

Application filed April 21, 1899. Serial No. 713,936. (No model.)

T0 [0 whom, it may concern:

Be it known that I, SIMON W. WARDWELL, Jr., a citizen of the UnitedStates, residing in the city and county of Providence, in the State ofRhode Island, have invented certain new and useful Improvements inMachines for Winding Heavy Twine, of which the following is aspecification.

My invention relates to machines for winding cops such as are set forthin my Letters Patent No. 480,157, and relates to certain details ofconstruction fully set forth hereinafterand illustrated in theaccompanying drawings, in which Figure l is a front elevation of amachine embodying my improvements. Fig. 2 is an end elevation. Fig.3 isan elevation, enlarged, of the cord-guide and operating parts connectedtherewith. Fig. 4 is an enlarged section on the line 4. 4, Fig. 3. Fig.5 is an enlarged end view looking in the direction of the arrow 1, Fig.3. Fig. 6 is an enlarged sectional view of the parts at the right ofFig. 3. Fig. 7 is a section on the line 7 7, Fig. 6,1001:- ing in thedirection of the arrow. Fig. 8 is an enlarged sectional view of theexpansionpulley on the line 8 8. Fig. 9 is a face view of Fig. 8. Fig.10 is a section of a modified expansion-pulley. Fig. 11 isaface viewthereof, and Fig. 12 is an edge view thereof.

The machine consists, essentially, of a main frame A, supporting thewinding-spindle W, the end of which constitutes a cop-holder w, aswinging frame F, supporting the reciprocating guide and its drivingconnections, and suitable connect-ions whereby the reciprocating guideis positively driven in conjunction with the winding-spindle.

As shown in the accompanying drawings, the machine is driven by means oftight and loose pulleys of ordinary construction applied to thewinding-spindle \V, whence motion is transmitted, through the beltconnection L, the two shafts 26 and 25, and suitable gearingconnections, to the reciprocating guide I, termed herein the cord-guideand as her einafter described.

The reciprocating guide is made of any desired form adapted to thematerial to be wound, provided, preferably, with a groove or channelsuitably formed and disposed to receive the material and deliverit tothe package being wound and with a broad flat'face' u to provideadequate bearing on the pack age to prevent the guide from indenting thepackage or unduly abrading the material wound. The edges of the bearingsurface are suitably formed to permit the guide to ride across the coilswithout displacing them.

The guide I is carried on and driven by the helically-grooved shaft D,which for convenience I term the screw, and is prevented from turningtherewith by means of the guiderod 6. Adapted to slide in one of thehelical grooves is the shoe 52, Fig. 4, which is so connected with theguide by the screw that as the screw D rotates alternately in oppositedirections the latter imparts to the guide a 'reciprocating motion.

The screw D rotates in bearings d d on the top of the frame F andcarries at any suitable point two bevel-gears 31 and 32, each free torotate upon the screw and independent thereof, except as indicated.

At the top of the shaft 25 is the bevel-gear 29, which, meshing with thetwo gears 31 and 32, causes each to rotate in a direction opposite tothat of the other. Between these two gears is a clutch member 53,adapted to engage with each and provided with means whereby it can beshifted from engagement with one gear into engagement with the other toreverse its rotation. The clutch member, while free to slidelongitudinally on the screw D, is so connected therewith as to impartits motion of rotation in either direction. A transverse pin 23 connectsthe clutch member 53 with a rod 22, which extends through the hollow endof the screw D and projects beyond the same. This rod 22 is connectedwith a rod 0 by means of the arm H, which, secured at one end to the rod0, is at the other end provided with a fork, which fits in an annulargroove in a collar at the end of rod 22. The rod 22 is thus free at alltimes to rotate with the screw D, but can be shifted longitudinally bymeans of the rod 0 to throw the clutch from engagement with one gearinto engage ment with the other. I

The rod 0 is shifted at the end of each traverse from the guide I orsome part connected therewith, as by the guide I striking against 'oneor the other of the two contact-pieces, which may operate through anyintermediate IOO appliances to cause the shifting of the reversingdevices. As shown, there are two parts G G, which act as detents in oneposition, but when lifted release the shifting devices. Each part Gengages a contact-piece g, which is adjustable in position on the rod 0.

It is obvious that any friction between the cars a of the guideI and theshifter-rod c or the jar of the'machine might disengage the clutchbefore the proper time for such disengagement, and for this reason Iprovide positivelyacting detents. The latter are pivoted to the supports24, which are adjustable in position on the guide-rod e. Each of thesedetents has a shoulder 4, adapted to a correspondingshoulder on thecontact-piece g, and is depressed by the spring t, so that the twoshoulders engage in one position of the parts. The extremity of eachdetent is beveled and the guide I provided with suitable projections 7O70, adapted to engage with each detent at each end of the traverse tolift the detent and allow the rod 0 to be shifted directly or indirectlyto reverse the motion of the screw. With aclutch mechanism of thisdescription, in which the direction of rotation of one memher isreversed by throwing it alternately from engagement with one intoengagement with another of two other oppositely-rotating members, it isessential that one side of the clutch be disengaged before the otherside is engaged. There is, in consequence, during the operation ofreversing the motion of the first member, a momentary period duringwhich it is unconnected with the driving mechanism, and hence isneutral, being inoperative to drive the parts to which it is connected.

If the guide I ran at very high speed and any projection from the guidestruck directly a contact-piece upon the rod 0, there might besufficient momentum in the shifting parts to carry the clutch from onegear into engagement with the other; but this is not positive and sure,especially at slow speeds, and I therefore provide an independent meansfor shifting the parts, arranged to operate When the detents G G arelifted. Thus I arrange on the rod 0, adjacent to the contact-pieces g g,springs 42 42, adapted to be compressed by the ears a as the guide Iapproaches either end of the traverse. By this means suflicient power isstored up prior to each movement of the clutch to throw the latterpositively into engagement with one gear after it has been disengagedfrom the other, and this results regardless of the speed of movement ofthe guide.

In order to vary the length of the cop, I vary the extent of thetraverse of the guide by shifting the position of the parts 24, g, and42, as before described.

Fig. 3 shows the position of the parts just after the clutch has beenthrown into engagement with the gear 32. One of the projections of theguide I has lifted the left-hand detent G front engagement with thecontactpiece g. The car a, pressing against the G011- tact-pieee g aftercompressing the spring 42, has forced the clutch out of engagement withthe gear 31, and the spring 42, compressed as stated, has carried theclutch into engagement with the gear 32. The guide, as shown, is nowmoving toward the right. As it approaches the opposite end of itstraverse it will compress the spring 42, one of the projections 70 willlift the detent G, and the car a will strike the stop g and force theclutch out of engagement with the gear 32, the compressed spring 42completing and insuring the instant movement of the clutch, throwing itinto engagement with the gear 31. As the rod 0 moves to the right theshoulder 3 of the contact-piece g at the left-hand end of the traversewill have passed the corresponding shoulder 4 on the detent G, allowingthe latter to dropinto position to prevent the movement of the rod 0 tothe left until the contact is again raised by the approaching guide.

In order to prevent the engaging parts of the clutch device frombecoming clogged and ineffective, the cluteh-sleeve 53 is covered by aband 53, Figs. 3 and 6.

The frame F is provided with a counterweight 59, which swings the frameinward and tends to maintain the contact of the guide and cop orpackage. In winding any material various conditions are encounteredwhich tend to distort the package. Thus the heavy material for whichthis character of machine is more especially intended frequently variesin diameter and density. In starting a package the coils sometimes drawback from the ends of the package, and in the course of winding bunches,knots, and splices are encountered in the cord. If the guide pressed atall times with equal pressure against the package,it would follow theirregu larities of the latter, sometitnes accentuating them andpresenting an irregular and unsightly package. These effects may beovercome by preventing the inward movement of the guide after it hasbeen forced outward, and I show in Figs. 6 and 7 an improved devicewhereby the guide is restrained from returning to the spindle after ithas been carried outward. In said figures there is a bearing-bar Q,pivoted or otherwise secured to the frame A and shown as curvedconcentrically with the axis of the frame I and resting upon a lug ofthe frame F. Pivoted to the frame is a wedge P, bearing upon the bar Qwith its curved edge and weighted to maintain contact therewith, theconstruction being such that the frame F can move away from the spindlein the direction of the arrow, Fig. 7, without material resistance, butis prevented by the wedge from returning. By pressing upon a finger 76,however, the wedge may be lifted to permit the frame to be swung inwardwhen required.

The position of the above parts might be altered without changing theeffect by conmeeting the part Q to the frame F and the parts P 75 to themain frame, and it is evident that the wedge could be arranged to bearupon either edge of the bar Q.

It is desirable in this class of machines to provide means forpositively and accurately regulating the relative movements of therotating winding-spindle and the reciprocating guide. I use for thismeans, in the construction shown, an adjustable expansion-pulley L ofimproved structure. Heretofore, expansion-pulleys have been used,provided with a V-shaped groove adapted to a correspondingly-shapedV-belt. This, while one of the most efficient devices foraceomplishingthe desired regulation in speed, is open to the following objections:First, the specially-formed V-beit is expensive to manufacture, owing tothe fact that it must be accurately formed to uniform cross-section;second, owing to the stiffness of a V-section such a belt is much lessflexible than a flat one and does not obtain so good a bearing on thepulley; third, the V- belt is not available for use on machines thatwind heavy material, because it is diiiicult to obtain leather ofsufficientthickness forsuch heavy belts as would be needed; fourth, whenthe eXpansion-pulleyis adjusted it presents a greater or less surface tothe belt, depending on whether the two halves are separated or closedtogether, and, fifth, as the leather becomes more pliable from use andfrom the oil absorbed it sinks more deeply into the pulley, thuschanging the pitch-line of the pulley and causing the wind to change. Inmy new and improved construction I overcome these faults by the use ofan expansion band or ring whose inner face is fitted to the V-groove inthe pulley and having a substair tially flat outer face adapted toreceive a fiat belt. By this means I am enabled to use a thin flexiblebelt of any desired width which will readily adapt itself to theperiphery of the pulley, insuring the maximum surface of contact and ofsufficieni width to transmit great power. As shown in Figs. 8 and 9, theparts 61 are the parts of the expansionpulley having beveled edgesadapted to the beveled inner face of the split ring or band 73, from oneend of which a pin 76 projects inward into a hole in a pin 77, extendingloosely through both parts of the expansion pulley. The pin '76 must beso located relative to the movementof rotation of the pul ley that theend of the band secured by the pin will first come in contact with thebelt, whereby the latter will tend to press the band more firmly intothe groove. In other words, the pressure of the belt tends to carry theparts of the band away from the pin. If the reverse was the case, theparts of the band would be pushed toward the pin, causing the band todistend and altering the timing of the machine, or breaking the ring ifmade of cast metai, as is the cheapest mode of manufacture.

In the construction shown in Figs. 8 and 9 the disk 60 is clamped to theshaft, which may or may not be the winding-spindle, and the disk ()1slides upon the shaft, which is provided with a screw-thread receivingan adjusting-nut 7-1, the latter having a slots and binding-screw 79,whereby it may be clamped firmly in position upon the shaft.

In the construct-ion shown in Figs. 10, 11, and 12 the hub 63 of thefixed disk 60 is threaded, shown, and the disk 61 slides upon saidhuband is provided with an internally-threaded collar 74, which has aslot 8 and binding-screw 79 and serves the purpose of the nut 74, Fig.8. In the construction of Figs. IO, 11, and 12 the pin 77 of Fig. 8could not be used, as in adjusting one disk is turned independently ofthe other, and the pin 76 is therefore extended into a slot 78 in thedisk 60.

The belt L, Figs. 1 and 2, passes from the expansion-pulley L to apulley L the shaft of which is carried by a frame K, swinging about theaxis 26 as a center and provided with a gear-wheel 8, meshing with agear- Wheel9,on the shaft of the pnlleyL the frame K having a Weight 10connected therewith to maintain the belt taut.

While I have described and shown the band 73 upon the expansion-pulleyas consisting of a single split ring, it may consist of sections of aring, each secured preferably at one end, so as to turn with the disksof the pulley.
